4-Ethyloctanoic acid(CAS: 16493-80-4)

4-Ethyloctanoic acid is a colorless or light yellow liquid with a pungent odor. Its molecular weight is 170.24 g/mol. It has a melting point of -32°C and a boiling point of 283°C. It is slightly soluble in water but miscible with organic solvents like ethanol and acetone. It is reactive, forming esters and amides easily under basic conditions.

4-Ethyloctanoic acid is typically synthesized by the hydrolysis of ethyl 8-oxooctanoate, which is obtained by the reaction of 1-oxooctanoic anhydride with ethanol. The synthesis involves basic hydrolysis under controlled conditions to yield the desired acid with good yield and selectivity.

4-Ethyloctanoic acid is used in the pharmaceutical industry for the synthesis of certain drugs, and in the polymer industry for producing copolymers. It also finds applications in the production of sensors and as a reagent in organic synthesis. Its use in semiconductors is limited.

Handling 4-Ethyloctanoic acid should be done in a well-ventilated area and with appropriate personal protective equipment (PPE) such as gloves and safety goggles. It should be stored in a closed container away from heat and sources of ignition. In case of a spill, it should be handled according to the Material Safety Data Sheet (MSDS/SDS).
